2.2
RXD-Pin
This pin reports the state of the LIN bus voltage to the protocol controller. A LIN-low-level (dominant state) is transmitted as a CMOS-low-level. A recessive LIN-state (LIN-high-level) is transmitted as a CMOS-high-level. The RXD output structure is an open-drain output stage. This allows the ZMD30011 to be used with 3.3 V or 5 V I/O protocol controllers. If the controller's RXD pin does not have an integrated pull-up, an external pull-up resistor to the microcontroller I/O supply voltage is required. The driver is tristated in the sleep-mode.
2.3
EN-Pin
This input determines the operation mode of the device. EN=high sets the device to the normal-mode, EN=low sets the device to the sleep-mode significantly reducing the current consumption. If the signal is floating then the EN-pin is held on low by an internal pull-down-resistor. The pull-down-current is restricted to 25 A typically.
2.4
WAKE-Pin
The wake-pin is a high-voltage-input. A low-signal from the system (trigger) wakes up the transceiver from the sleep-mode (local wake-up). An input filter prevents unintended wake-up in the case of transients. An internal pullup-resistor prevents floating of the pin in the unconnected state. If the application does not require a local wake-up than the wake-pin has to be connected with VSUP.

2.5
TXD-Pin
This CMOS-input connects the external protocol controller to the transceiver. A TXD-low-level is transmitted as a LIN-low-level too. The LIN-driver is tristated if TXD is high, hence the bus is set to recessive state using the pull-upresistor. The TXD-input is equipped with an internal pull-down resistor and an internal timer preventing the LIN-bus from being permanently driven in the dominant state.
2.6
GND-Pin
The GND-pin represents the ground level. Level suspensions 2 V do not influence the data transfer. A ground loss in the recessive state does not lead to a significant current at the LIN-pin.
2.7
LIN-Bus-Pin
The circuit blocks receiver and transmitter realize the bi-directional LIN-bus-connection. Receiver: The input voltage of the receiver depends on the supply voltage ratiometricly. The threshold amounts to 0.4 respective 0.6 VSUP with a typical hysteresis of 10 % VSUP. The receiver is active in the sleep mode too. The filter in the input signal path suppresses spikes with a duration of < 4 s. Transmitter: The transmitter consists of a low-side-driver supplying 20 mA at a typical output-voltage of 1 V. It transmits a low level if there is a low level on the TXD-pin. An internal pull-up resistor of 30 k pushes the bus node to the high level in the locked transmitter state. A diode is located in series to the resistor and prevents a reflow current from the bus into the battery supply line in the case of a local supply loss or a ground level shift. The transmitter is only active in the normal-mode. In the sleep-mode and in the wait-mode the transmitter is tristated. A slope-control adjusts both edges (falling edge from the recessive to the dominant driver state and rising edge from the dominant to the recessive driver state) to 2V/s typically. As a result the electromagnetic emission is minimal. The capacitive LIN-bus-load has to be restricted to a total of <=10 nF at a total resistance 0.5 k in order to ensure the symmetry of both edges. In the case of short circuits to battery supply the drivers current limitation begins to work at 180 mA typical. The driver is also protected against thermal overloads. In the range from -18 V to 30 V the current VSUP-LIN is determined only by the pull-up-resistor. A VSUP loss in the recessive driver state does not lead to a significant current at the LIN-pin.
2.8
VSUP-Pin
The VSUP-pin has to be protected by an external diode against reverse polarity of the battery supply. The protection against galvanic and capacitive coupled transients is realized by a special internal circuitry. The operational supply voltage reaches from 6.5 to 18 V DC. A voltage control prevents an incorrect bus transfer below the operating voltage range. The quiescent current in the sleep-mode amounts to typical 14 A. In the normal-mode the quiescent current amounts to max. 2 mA in the state of dominant LIN-bus.

2.9
INH-Pin
The INH-pin ("inhibit-pin") is a high-voltage-output controlled by the EN-input. In the normal-mode and in the waitmode the inhibit high-side-driver sets INH=VSUP (EN=high). The INH-pin may be used to switch on an external regulator or to set external switches active for an interrupt request. The inhibit-driver is capable to source 40mA typically. If EN is set to low then the transceiver switches to the sleep-mode and separates external modules from VSUP by tristating the INH-pin. Hence, a voltage regulator with its inhibit pin connected to INH will be disabled. If the master node pull-up resistor is connected to INH then it will be disabled from the LIN bus. A WAKE-UP-event or EN=high sets INH=high.

3. Functional Description
3.1 Sequence Control
The internal sequence control manages the operation modi and their transient states (see figure 2). normal-mode: sleep-mode: INH=high, EN=high, bus transfer permitted INH tristated, EN=low, only bus reception possible The receiver stands in the active state and the driver is tristated. Setting EN to high brings the transceiver into the normal-mode. Applying Wake=high at the WAKE pin or a LIN bus wake-up message bring the device into the wait-mode. wait-mode: INH=high, EN=low, bus transfer impossible, Switching EN to high switches the transceiver into the normal-mode from another mode. The transceiver switches to the power-down state from any operation mode if VSUP falls below 6.5 V. As soon as VSUP rises over 6.5V again the transceiver changes from power-down into the wait-mode. The transceiver changes into the wait-mode too from another mode if the junction temperature rises over 150C. The change from wait-mode into the normal mode is caused by setting EN to high.
3.2
Wake-Up-Events
There are three methods how to wake up the transceiver from sleep-mode: (1) Wake-up by WAKE-pin active An internal timer supervises the level at the WAKE-pin. If the WAKE-level falls from WAKE-high to WAKE-low and stays there for minimal 40s than the timer activates the INH-output. The transceiver switches into the wait-mode within maximal 150 s after the falling edge of the WAKE pin. By doing so spike pulses are filtered out effectively. When the external regulator has reached its output level and the system is ready than the protocol-controller switches EN=high. The transceiver changes into to the normal-mode and gets ready for bus transfers. (2) Wake-up by bus-message: The reception of a LIN-low-level (dominant state for 250 s to 5ms) in the sleep-mode triggers the following wakeup-sequence: At the latest 150 s after the falling edge of the LIN signal the transceiver activates the system's voltage regulator by setting INH=high and goes to the wait-mode. After a system reaction time (until regulator and application active) the protocol-controller sets EN=high. The device switches to the normal-mode and gets ready for bus transfers. An antibounce filter suppresses spike pulses from the LIN bus. (3) Wake-up by EN-pin active: There are systems with an external power supply which are also active in the LIN-transceiver's sleep-mode. If the application of such a system gets active then the protocol controller sets EN=high. The transceiver switches to normal-mode at once and is ready for the transfer of a wake-up-frame from the protocol controller to the LIN-bus. In such applications the INH-pin can be used for other purposes, e.g. for an interrupt request.

3.3
TXD Dominant Time-out Function
An internal timer prevents the LIN-bus from being permanently driven in dominant state. If TXD is at low level for longer than tBus_dom > tTXDTIMEOUT the pin LIN is switched of to recessive mode. To reset this mode the pin TXD has to be switched high before switching LIN to dominant state again.
3.4
Internal Voltage Regulator
The transceiver has an internal voltage regulator generating a voltage VDD=5V from the battery supply VSUP. This works in all operation modes. In the sleep-mode this voltage regulator changes into a low-power-mode. This mode guaranties the supply of the receiver and the sequence control.
3.5
Battery Voltage Control
The battery voltage control is realized indirectly by a power-on-clear-circuit supervising the internal supply VDD. This circuit gives a signal to the sequence control if the external supply voltage VSUP falls below 6.5V. In this case a contingent bus transfer can be prevented and the transceiver changes into the wait-mode.
3.6
3.3V and 5V Logic Capability
The ZMD30011 can be used for 3.3V and 5V micro controllers. EN, RXD and TXD are capable to operate with both voltage levels. Therefore an external pull-up resistor is required at the RXD pin.

4. Electromagnetic Compatibility and Short-circuit Immunity
Electromagnetic Emission: The built-in slope-control adjusts the slew rates to 2 V/s for the rising and the falling edges. As a result the electromagnetic emission is at a minimum. Electromagnetic Sensitivity: The pins LIN, WAKE, VSUP and INH are equipped with protective circuits resistant to electromagnetic imission. The ESD-protection at these pins is guaranteed for 8 kV (Human Body Model). The protection against transients (test impulses 1...3 according to ISO 7637/1) is improved by the external slave- or master-capacitors between VSUP and GND and between LIN and GND. Short Circuit Immunity: The LIN-interface is short-circuit-proof against VSUP and ground.
5. Fail-Safe-Features
Short-circuit at LIN The current of the transmitter output stage is limited to ILIM in order to protect the transmitter against short-circuit to VBAT or GND. In case of such a short-circuit the temperature exceeds the shutdown temperature TSHUT due to the power dissipation - the ZMD30011 goes into the wait-mode and the transmitter switches off. The ZMD30011 has a special circuitry implemented that protects the battery from running out of charge in the case of a short circuit between LIN and GND. In this failure case a normal master termination (1k resistor and diode in series between LIN and VSUP) would cause a constant current flowing through the termination resistor (even in sleep mode). In order to use this feature the master termination resistor has to be connected to the INH pin instead of VSUP. Loss of Ground or VSUP A loss of power (pins GND or VSUP) has no impact to the bus line and the protocol handler. Since there are no reverse currents from the bus the LIN transceiver can be disconnected from the power supply without influencing the LIN bus. Pin RXD is set floating if VSUP is disconnected. Thermal Overload The output driver at pin LIN is protected against thermal overload conditions. If the junction temperature exceeds the shutdown temperature TSHUT, the thermal protection circuit disables the output driver. The driver is enabled again if the junction temperature has been decreased by about THYST. TXD Disconnection Pin TXD is equipped with an internal pull-down resistor to provide a static low if TXD is disconnected. The LIN line is prevented from being permanently driven in dominant state by an internal timer. EN Disconnection Pin EN provides an internal pull-down resistor in order to force the transceiver into sleep mode in case the pin EN is unsupplied.
